The invention relates to a monitoring system and method for reducing the false alarm rate of driver distraction identification. The system comprises a hardware end and a software end. The hardware end is a camera, an ISP firmware program is integrated in the camera, and the hardware end is responsible for processing an image and realizing quality adjustment of the image; the software end is an SDK algorithm package module. The method comprises a first acquisition stage and a continuous acquisition stage, the first acquisition stage is carried out after equipment is powered down or a program is forcibly restarted, and the continuous acquisition stage is always carried out after the first acquisition is successful until the driving is finished; according to the method, for the same driver, in the same driving process, according to a strategy obtained by the head positive direction, the head positive direction of the driver is updated in real time, then judgment conditions and suppression conditions are overlaid, distracted driving reminding is carried out, and distracted false alarms generated by different driving postures of the same driver can be reduced; and for different drivers, different head posture coordinate systems can be switched according to real-time updating of the positive direction of the head, so that distraction false alarms are reduced.
本发明涉及一种降低驾驶员驾驶分心识别误报率的监测系统及方法。系统包括硬件端和软件端;硬件端为摄像头,其内集成ISP固件程序,负责处理图像,实现图像的质量调节;软件端为SDK算法包模块。方法分为首次获取和持续获取两种阶段,在设备掉电或程序被强制重启后,会进行首次获取,在首次获取成功后将一直进行持续获取,直至本次行驶完毕;本方法对于同一驾驶员,在同一次驾驶过程中,依据头部正方向获取的策略,实时更新驾驶员的头部正方向,再叠加判断条件及抑制条件,进行分心驾驶的提醒,可降低因同一驾驶员的不同驾驶姿态产生的分心误报;对于不同驾驶员,也可根据头部正方向的实时更新,切换不同的头部姿态坐标系,进而降低分心误报。
